This Business Analysis Guidebook is designed to facilitate a consistent approach in the use of the tools and techniques contained within the Business Analyst profession. The primary goal is to provide a simple "how to" guide for new and non-Business Analysts for gathering (eliciting) and documenting business requirements--whether they are at the process, project or enterprise level. The material linked below was initially authored by a group of Business Analyst professionals within NYS Government, and it is hoped that the list of contributors (included in later chapters) will grow. We are currently weaving our content together--so please pardon our duplication and inconsistent formatting. It is our intent to have this material be licensed under Creative Commons Attribution-Share Alike 3.0 Unported License and the GNU Free Documentation License, both included at the end of this document.
